Abstract

본 발명의 스크롤압축기는 정상운전시에는 종래의 스크롤압축기와 같은 축선방향의 콤플라이언트가 실현된다. 즉, 판형의 나선으로 감긴 톱니의 톱니선단과 톱니바닥이 항상 가벼운 접촉력을 갖고 미그러짐과 아울러 기동시에 있어서도 정지시의 양스크롤이 축선방향으로 이격되는 상태로부터 미그럼운동스크롤이 프레임과 일 체로 되어 안정된 자세를 유지하면서 서서히 고정스크롤과의 거리를 좁혀서 정상운전시의 상태로 이행함으로써 고성능이고 저소음적이며 고신뢰성을 갖는 스크롤압축기가 얻어진다.The scroll compressor of the present invention realizes the axial compliance as in the conventional scroll compressor in the normal operation. In other words, the tooth tip and the tooth bottom of the tooth wound with plate-shaped spirals always have light contact force, and the migratory motion scroll becomes integral with the frame from the state in which both scrolls at the time of stopping are axially spaced even at the time of starting. By gradually narrowing the distance to the fixed scroll while maintaining a stable posture, the scroll compressor has a high performance, low noise and high reliability.
